Electric car maker Tesla said Tuesday that it is launching a 100-kilowatt-hour (kWh) battery for its Model S and Model X cars. A report on Bloomberg says: Tesla is adding versions of its Model S sedan and Model X sport utility vehicle with a more powerful battery pack that the company said makes the Model S the world's quickest production car and gives it range of 315 miles on a single charge. Chief Executive Officer Elon Musk is trying to appeal to sports car enthusiasts with the new Model S P100D with a 100 kilowatt-hour battery, which with Ludicrous mode can go from a standstill to 60 miles per hour in 2.5 seconds, compared with 2.8 seconds for the P90D Ludicrous version. The P100D Ludicrous upgrade costs $10,000 for customers who have ordered a P90D Ludicrous but haven't taken delivery, or $20,000 for owners who already have that vehicle type.

Facebook knows a lot more about its users than they think. For instance, the New York Times reports, the company is categorizing its users as liberal, conservative, or moderate. These details are valuable for advertisers and campaign managers, especially ahead of the election season. From a BusinessInsider report: For some, Facebook is able to come to conclusions about your political leanings easily, if you mention a political party on your page. For those that are less open about politics on social media, Facebook makes assumptions based on pages you like. As The New York Times explained, if you like Ben and Jerry's Facebook page and most of the other people that like that page identify as liberal, Facebook might assume you too are liberal.

Researchers have developed in collaboration with French colleagues a small device that both detects the initial signal of an epileptic attack and doses a substance that effectively stops it. All this takes place where the signal arises -- in an area of size 20chr('215')20 μm known as a 'neural pixel.'

A recent study published by Brazilian researchers indicates brain malformations induced by Zika virus congenital infection. More than microcephaly, the research indicates other neurological changes such as reduction in brain volume, cortical development abnormalities and ventriculomegaly.

Insufficient capacity to perform laboratory tests used in monitoring HIV infection, and underutilization of existing testing capacity, are limiting the ability to meet the Joint United Nations Programme on HIV and AIDS 90-90-90 targets, suggests a new study.

Traumatic brain injury (TBI) during youth is associated with elevated risks of impaired adult functioning, according to a longitudinal study. The study demonstrates that children and adolescents experiencing even milder forms of TBI (including concussion) may have reduced longevity and significant psychosocial problems in adulthood.

PlayStation 3 games are coming to Windows. Sony said Tuesday that it is bringing its PlayStation Now game-streaming program to Windows PCs. The service broadcasts PlayStation 3 games over the internet similar to the way Netflix beams movies to devices like Roku. CNET reports: This fall, you'll be able to play previously exclusive games like Uncharted 3 and Shadow of the Colossus on a Windows laptop. The catch: you'll be playing those games over the internet with Sony's streaming game service, PlayStation Now. Think Netflix. PlayStation Now has already been around for a couple of years on the PS4, PS3, PS Vita handheld, plus a handful of Blu-ray players and smart TVs. For $20 a month or $45 for three, the service gives players unlimited access to a long list of over 400 PlayStation 3 games. Like Netflix or any other streaming service, the quality can vary wildly depending on your internet connection -- Sony requires a solid 5Mbps connection at all times, and that doesn't change today. What changes is the size of Sony's audience. With a Windows laptop or tablet, you aren't tethered to a big-screen TV. You could theoretically take these PlayStation games anywhere -- and wherever you go, your save games stream with you.

Hackers thought to be working for Russian intelligence have carried out a series of cyber breaches targeting reporters at the New York Times and other U.S. news organizations, reports CNN, citing US officials briefed on the matter. From the report: The intrusions, detected in recent months, are under investigation by the FBI and other US security agencies. Investigators so far believe that Russian intelligence is likely behind the attacks and that Russian hackers are targeting news organizations as part of a broader series of hacks that also have focused on Democratic Party organizations, the officials said. "Like most news organizations we are vigilant about guarding against attempts to hack into our systems," said New York Times Co. spokeswoman Eileen Murphy. "There are a variety of approaches we take up to and including working with outside investigators and law enforcement. We won't comment on any specific attempt to gain unauthorized access to The Times." The breaches targeting reporters and news organizations are part of an apparent surge in cyber attacks in the past year against entities beyond US government agencies.

Researchers have demonstrated the 3-D printing of shape-shifting structures that can fold or unfold to reshape themselves when exposed to heat or electricity, an approach also known as '4-D printing.' The micro-architected structures, including boxes, conductive devices, and a stent, were fabricated from a conductive, environmentally responsive 'smart' ink.

We've talked extensively about the missing headphone jack on the upcoming iPhone. While some say that the move will ruin user experience -- something that has already started to seem that way in the real world -- a few argue that someone needs to push the needle to move the technology forward. Now Apple co-founder Steve Wozniak has something to say about the missing legacy audio jack as well. He is asking Apple to fix the Bluetooth first if the company intends to give users to move to wireless headphones. From a Financial Review report: Apple co-founder Steve Wozniak has warned Apple is going to frustrate a lot of customers if it removes the headphone jack from the upcoming iPhone 7. [...] Customers wanting to use their existing, wired earbuds and headphones might have to buy an adaptor that attaches to the iPhone's Lightning port, or to whatever port does remain on the phone. "If it's missing the 3.5mm earphone jack, that's going to tick off a lot of people," Mr Wozniak told The Australian Financial Review. "I would not use Bluetooth ... I don't like wireless. I have cars where you can plug in the music, or go through Bluetooth, and Bluetooth just sounds so flat for the same music." Mr Wozniak said he would probably use the adaptor to connect his existing earphones to his next iPhone, and said that, like many other users he is attached to the accessories that he uses alongside the phone. "Mine have custom ear implants, they fit in so comfortably, I can sleep on them and everything. And they only come out with one kind of jack, so ''ll have to go through the adaptor," he said. "If there's a Bluetooth 2 that has higher bandwidth and better quality, that sounds like real music, I would use it. But we'll see. Apple is good at moving towards the future, and I like to follow that."

A new class of fuel cells based on a newly discovered polymer-based material could bridge the gap between the operating temperature ranges of two existing types of polymer fuel cells, a breakthrough with the potential to accelerate the commercialization of low-cost fuel cells for automotive and stationary applications.

Extensive systems of fossilized riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according to new research.

An anonymous reader writes: Ride-hailing giant Didi Chuxing is adding a car rental service for customers in several cities, to take advantage of the enormous domestic tourism market in China. Users can reserve a car through the Didi app and have it delivered to their door within two hours. The service, which is currently in beta testing in Shanghai, is expected to expand to several more cities in China over the next year. In a statement the company said, "Didi car rental is launched in response to the boom in China's short-term and tourist car rental market as the population goes through a lifestyle revolution." In 2015, 2.34 billion cars were rented for domestic tourists in China. That number is expected to more than double, reaching 5.8 billion by 2020.The move comes weeks after Uber announced it was selling its Chinese operation to Didi.
